Starting to Build

Let’s get started!

Task 1: Create the folder structure in your working directory as shown below.

 

If you have both your UI and Server code in one R script, your folder should look like the following:

 

Task 2: Create Shiny script and load Shiny library.

 

To create your first Shiny app you have two options:

1. Open a new script and insert the following:

library(shiny)

ui <- fluidPage()

server <- function(input, output) {}

shinyApp(ui = ui, server = server)

 

2. While in your working directory (as created above), go to File–> New File–> Shiny Web App.This option will create a Shiny App in two scripts rather than one.
   

 

Task 3: Your app will be empty or will contain default code. Test Shiny works by running your app as shown below.
